WeddingMapper, enables couples who are tying the knot an easy way to map the festivities for guests.
The user can add various markers to an online map — such as “ceremony,” “reception,” “hotel,” or “airport” — to show where the locations are in relation to one another and then can supplement the marker with web links, uploaded photos and custom descriptions.
View wedding locations on a map or on a nicely-formatted list. There are so many online wedding planner apps out there, but this seems particularly useful for your guests coming in from out of town.  Gina Trapani
